[jQuery] Ajax reacts very slow...?

[jQuery] Ajax reacts very slow...?


Hi,
I have this function build:
$.ajax({
            type: "POST",
            url: "/ajax_add_selected_product_to_session.php?global_check",
            success: function(msg){
                /* add here what to do on success */
                //alert(msg);
                howmanyfromsession = msg;
                if (howmanyfromsession == 1){
                    $(".amount").empty();
                    $(".amount").append(' (Derzeit ist ' + howmanyfromsession + '
Produkt vorgemerkt)');
                }else if(howmanyfromsession > 1){
                    $(".amount").empty();
                    $(".amount").append(' (Derzeit sind ' + howmanyfromsession + '
Produkte vorgemerkt)');
                }else if(howmanyfromsession == 0){
                    $(".amount").empty();
                }
                if(howmanyonpage == 0 && howmanyfromsession == 0) {
                 //alert('None are checked on page');
                    $(".requestbutton").attr("disabled", "disabled");
                }else if(howmanyonpage == 0 && howmanyfromsession > 0){
                    //alert('At least one is checked');
                    $(".requestbutton").removeAttr("disabled");
                    $(".requestbutton").click(function(){
                        $("#list").submit();
                    });
                }
                $(".requestbutton").click(function(){
                    if($("input[name^='paradigm']:checked").length > 0) {
                        $("#list").submit();
                    }
                });
            }
The part with:
$(".amount").append(' (Derzeit ist ' + howmanyfromsession + ' Produkt
vorgemerkt)');
takes really long at the moment. Is there a way to improve the speed?
If you want you can test it here:
http://packpilot.s15312582.onlinehome-server.info/search.php?action=list&prg_fkid_prg_id=81&prg_id=86
Look for the button "Für ausgewählte Artikel Herstelleranfrage senden"
on its right hand side a small text will appear, telling how many
products you have selected.
I don't understand why it takles so long...?
Any ideas?
